Application filed September 3.1 914. Serial No; 859,953.

To all whom, it may concern:

Be it known that I, J AMES J. OREGAN, a citizen of the United States, and a resident oi \Voodhaven, county of Queens, Long Island. New York, have invented certain new and useful Improvements in TypelYriting Machines. of which the following is a s 'iecification.

My invention relates to typewritlng machines, and particularly to, that class of typewriting machines, the writing of which may be read by blind persons.

The writing done by my machines con ists of projections embossed in the paper and arranged in groups. The projections of each group have :1. certain arrangement to represent different letters according to the Braille or other similar systems of writing. The projections are embossed in the paper by forcing the paper into le jiressions in the platen or die plate on the paper can rier ol' the machine by means of pins operated by the keys of the machine.

()ne object of my invention is to provide a simplified form of frame work for supporting the keys and the carriage by stamp ing a base, having key supports and guides, and a carrier bed, or support out of sheet metal, and securing these parts together in a simple way.

A further object is to rovide a simple form of carriage and escapement mechanism carried thereby and to mount the carriage and its support in a simplified way.

A further object is to provide a die plate by providing one of the longitudinal bars of the carriage with groups of depressions arranged throughout the length of the bar, said bar passing across the ends of. depression making bars, as the carriage moves under the action of a spring when released by the eseapement.

Although the disclosure of my invention herein shows its embodiment in a specific form of mechanism. I do not, howe er. a ish to l mit myself to this particular form. as i do not wish to be limited to the projection making bars cooperating with the recessed platen, but may extend my invention to mbody any means for recording a depression or' the key upon paper.

My invention further consists in the eombination and arrangement of parts. and in the features of certain of said parts. as will hereinafter with more particularity appear from the detailed description and accom- 'ianying drawings, in which- Figure- 1 represents a. top view,--of one form of device embodying my invention,- Fig. 2 represents a cross section of the same .leviee: --l.' ig. 3 represents top view of my device with the carriage removed and portions of the table broken away to more clearly show the mounting of the keys; Fig. i represents a front view with portions broken away: Fig. 5 is a view of the carriage from the under side, with parts broken away: Fig. 6 is a view similar to Fig. 3, with the keys removed: Fig. 7 is a front view of the base and table: Fig. 8 is a section 8-8 of Fig. 6, Fig. 9 is an end view of the base and table, and Fig. 10 is an enlarged detail view. i

The herein described embodiment of my invention. has a trame comprising a base 1, a carriage bed it! and a carriage 30 all of sheet metal. There are two openings stamped out of this base, so that base comprises the side bars 3 and the end bars i, and a center bar 5. Attached to. the end bars i are the flanges 2. which are bent upwardly. Attached to the center bar ifare the flanges 6 for supporting the keys, and a flange 7 for supporting the e cape-merit mechanism. Attached to two oi" the side bars are the upstanding flanges 7, having the openings 7" for guiding the operating keys. 8. The carriage bed 10 comprises a table top 11 and down ardly extepding end por-- tions 12. Attached to the end portions are lugs 13, which may be inserted within the openings 8, by spreading the end portions 12 apart. The resilience of the said end portions 12 thereupon holds said projections within said opening 8. As a further precaution, the ends of these projections= may be bent down iiat upon the flanges 2. These projections 13 are made in the operation of stamping out the carriage bed 10, as clearly appears from Figs. to 9. in the top of carriage bed '10 and ends 12. there cut an opening 14, and the opening 1. These openings extend throughout the length of the top of the table.

The carriage 30 comprises a flat base portion and two upwardly extending end portions 81. In these end portions mmounted the two rubber covered rollers 32. These In the fianges'i. there areop n gs rollers comprise the shafts 33 and the coveuwm ing 31-. The shafts are resilient and this resilience, with the resilience of the rubber, tends to securely hold the paper upon which the impressions are to be made the tint base oi the carriage comprises three iongitudinally extending bars, 35, 36 and 37. The bar 36 has one edge turned down to form a flange 38 and this liange extends into the slot in in the top oi the table, serving to guide. the carriage in its forward and back ward movements. At the ends of the bars and 36, small lugs 39 are left when the 'arriage is stamped out. lhe lugs 39 on the bar 36 are cut 0:11 of the lange 30 and extend down into the slot l and are bent under the table top. in the ends 12 of the table. just below the top 11 thereof, are the slots 40 and it, which open into the slots ll and 15 respectively. When the carriage is slid onto the table i'roin the end the lugs 39 pass freely through slots it) and 41. At the middle of the c irriage there are lugs in and i3, similar to the lugs only they are longer and will rot pass through the openings 40 and 41. iVhen the carriage is lirst slid onto the table, these lugs are left in their normal position. that is, in the same plane as the base of the carriage,that is. in the same plane as the bars doand 3-6 respectively. \Vlnzn the carriage has cen sld on far enough t bring these lugs within the rnds 12 of tin table, these lugs are bcnt underneath the edge the table top 11, and assist in bolding the carriage d wvn to the table top and when they strike either a: the ends 12 of the table, they limit the movement of the cari-iage. Pivoted to the flange T is the plate it, to which is secured a yielding member i5; pivoted to the ends of the carriage is an cscapement rack i6, which comprises a bar bent to comprise two parts at right angles. The pivots for this bar are at the extremity of one of the parts. and on the edge of the other of the parts are formed the teeth 4. which are spaced apart a distancito ali't the carriageto move the proper amount, as will hereinafter appear. Formed integ al with this bar, there is the upstanding lever 47 which. when pressed bachwardly, swings the bar around ts pivot. The yielding member l normally engages one of the teeth of he tat-l; and held against the plate 41 by the pressure of the carriage, caused by the age actuating mechanism hereinafter tit-scribed iittached to the ].'l;!tt' ii is a spare key 48. hen this he is prtzssed. the plate is oscillated so th it the yielding member i5 is swung out of engagement with a tooth of the rack. o that he plate 44: engages said tooth. The re hence of the yieldmcmbcr cau e it to spring away from the plate 4i. and when the hey i5 is released, the member 45 engages the next succeeding tooth and the plate 44 is swung out of engagement when the tooth, which it had tion. l hc carriage may be returned to its nornnzl position without swinging the capcincnt bar, because the pressures oi th teeth it on the yielding member n will cause said member to yield, ptfl'llilllzz he teeth to slide over it The operating Ltcys comprise iiat bars 5U. which pass tli."

P the uPcIllll' S ill the guide ititfiiii i g 1 and are journalcd on the bolt .31 which is held in the llangts 3. and jocrnalcd on the bolt 51. brtwccn the keys, are the s mring collars 52. Joined to the ends of the her :30 are the impression bars .33, which extend upwardl and through openings 5+ in the tabletop ll. Attached to the under s de of tin; table tor- .l is a reinforcing and guiding bioclt :r, int-big openings 5C- which register with the onituings Bl. Surrounding the brats 5-11 5 53' for liOltiillg tin keys in potwurn when the yoke it) is depressed by an} other hey. In the lower Lace of the bar 57 ot' the carriage them are formed depics ions 57 which are generlly conical. but which have rounded edges, so that an lllil l'tabiflll will be made by air.- rounded or conical ends 58 of the bars 53; even though the depressions 57 are not txactly in register with the openings 5%.

The bar 87 is pressed upwardly rclative to the ends of the carriage when the carriage is :tampcd out in order that a space may be proi ided between the bar 257 and tilt: able top for the papei'l. to pass through t'reely. 'lhe inner edge of this bar 37 is bent. upwardly at an angie to the table top to form a flange 59 so that between said flange .19 and the table top there is a guifl. for the paper as it leaves the rolls 3:2. 5 cured to the bar 35 of the carriage is a flat spring 0. which presses down one face of the cscapement bar H holding it in position, and extending )llUHII'drV from the upper part of the bar it is a lug (51 integral therewith. which rests upon the bar 35. and prcrents the cscapcmcnt bar from being swung out of alinement with the member i5 by the spring 30. A part of the metal which is cut out of one of the ends 12 to foini the slot 14 in thetable is bent around into two arms. 62 and (33. These arms are perforated at lit and inserted therein is a bar 65 to which is attached the inner end of a Spiral spring 65, the other end of he spiral spring being attached to the ent. of the carriage farthest from this spring mount at 66. The bar 65 is rotated to increase the tension of zfonm of a yoke 70 which extends forward and passes under all of the operating keys 50. An opening 71 in this yoke accommodates the key 48, and the spring 72 presses the yoke upward, so that upon every depression of a key 50, the escapement key is operated and the keys are held at the top of the guide openings 7 "J In the description and claims, wherever the term carriage bed is used, it is in, tended to define broadly a supporting means for the carriage and is not intended to be limited to the U shaped member embodied in the device described. In the description the member carrying the depressions 57 has been designated the bar 37. This member is in reality the platen, and will be referred to in the claims as such. It has groups of 6 deressions, one for each key, said grou s being spaced apart a distance eoual to t e distance between the teeth of the escapement rack.

In the operation of'the device, the paper P is inserted between the rolls 32 under the flange 59 and between the platen bar 37 and the table top. The characters are made by depressions of different combinations of the 6 keys 50 and the escapement permits the carriage to move along the proper distance between each character.
